I am new to riding motorcycles. have a 2013 streetbob. for the first 1000 miles havent really gone faster than 3500 rpm because the manual said not to. so now even though im past 1000 miles i feel afraid to run the engine faster than that feeling like it would not be good for it. Is this thinking correct or can I run it at 3500 rpm for 4000 rpm around twisties all day?
